The Tiniest Traps: Optical Manipulation Gets Smaller

Valerie Coffey

Arthur Ashkin ushered in the field of optical manipulation more than 40 years ago. Today, smaller and smaller tools, such as optical “nanotweezers” and precisely focused lasers, are becoming practical for controlling single cells, individual proteins, DNA and even the behavior of worms.


A Broadening Vision for Adaptive Optics

Traditionally, adaptive optics has been used to improve telescope optics. However, wavefront correction techniques have also given researchers novel ways of exploring human vision and enhancing microscopy techniques.

Satyendra Nath Bose and Bose-Einstein Statistics

Although not as well known as his contemporaries, Satyendra Nath Bose was arguably one of the most important scientists in the 20th century. His revolutionary way of viewing photon behavior and photon statistics—later known as Bose statistics—changed the field in a dramatic way.
